1、材料与方法 1.1超级微生物制剂对水产生物的安全性试验 1.1.1急性毒性试验:选用体长<3cm的鲤鱼鱼苗为试验材料,试验前驯养10天以上,驯养期间鱼的自然死亡率低于10％。试验方法为等对数间距直线内插法。 1.1.2鱼类致突变试验:选用当年生的体重为150±10g的鲤鱼鱼种为材料,将上述菌液经生理盐水稀释后进行腹腔注射染毒,每天 Materials and Methods 1.1 Safety Tests of Supermicrobials against Aquatic Organisms 1.1.1 Acute Toxicity Tests: The carp fry with the body length <3cm was selected as the test material and domesticated for more than 10 days before the test. The natural mortality rate of the fish during domestication was low At 10%. Test method for equal logarithmic spacing interpolation. 1.1.2 fish mutagenicity test: the annual body weight of 150 ± 10g of carp fingerlings as material, the above bacteria diluted by saline after intraperitoneal injection, every day
